To understand why a simple USB software tool cannot downgrade a PS4, you need to understand how Sony’s security works. The PS4 prevents firmware downgrades using two primary chips on the motherboard:
This is a preventative method. It only works if you plan ahead.
Can a downgrade tool fix this? Once the update is installed and the e-fuses are blown, there is no going back. Your only option is to wait for a new jailbreak for the higher firmware (which may take years) or sell the console and buy one on 9.00.
The primary driver for downgrading is . Sony consistently patches exploits with new firmware updates; therefore, a console running a newer version is often "locked" from a user’s perspective. By downgrading to a specific version—most notably firmware 9.00 or 11.00 —users gain the ability to run custom software, install mods, back up games, and regain control over the hardware they own.
